Izidingo ezintathu ezinkulu zebhethri yokugcina amandla, ukuphepha yikona okubaluleke kakhulu
Isitoreji samandla e-electrochemical sibhekwa njengendlela eyinhloko yokugcina amandla ohlelweni lwamandla lwesikhathi esizayo, ibhethri ne-PCS iyinani eliphakeme kakhulu kanye nezithiyo kuchungechunge lwemboni, isidingo esiyinhloko silele ekuphepheni okuphezulu, impilo ende kanye nezindleko eziphansi. Phakathi kwazo, ukuphepha kuyisihluthulelo. Abanye ochwepheshe bezimboni bathi, manje isikhungo samandla okugcina amandla e-electrochemical sikhula ngokushesha, kepha udaba lokuphepha luyibhodlela lentuthuko enkulu, isikhungo samandla okugcina amandla eBeijing kanye nephrojekthi yokugcina amandla kaTesla Australia yokuqhuma futhi embonini yokugcina amandla. kukhale i-alamu.
Kuze kube manje, Imibono Eqondisayo Ekusheshiseni Ukuthuthukiswa Kwesitoreji Samandla Esisha ibeka phambili ukusungulwa kwamazinga obuchwepheshe bokuphepha kanye nesistimu yokuphatha, ukuqinisa ukuphathwa kokuphepha komlilo, ukuthobela ngokuqinile umgomo oyisisekelo wezokuphepha njengomgomo oyisisekelo; ekuphepheni okuphezulu, izindleko eziphansi, ukwethembeka okuphezulu, impilo ende kanye nezinye izici zenqubekelaphambili ende; qinisa ukuphepha kocwaningo lobuchwepheshe bokugcina amandla e-electrochemical nokunye. IKhomishana Kazwelonke Yezokuthuthukiswa Nezinguquko, Ibhodi Likazwelonke Lamandla ukuze lihlele ukubhalwa "Kwezinyathelo Zesikhashana Zokulawulwa Okuphephile Kweziteshi Zokugcina Amandla E-Electrochemical (Okusalungiswa)", nayo ibe ngomhla zingama-24 ku-Agasti emphakathini ukuze kuboniswane nomphakathi, ukuqinisa ukuphathwa. yokuphepha kokugcinwa kwamandla.
Ukuphepha okuphezulu, impilo ende, ukugqama kwenani lebhethri le-nickel-metal hydride
Idatha ye-China Battery Industry Association ibonisa ukuthi ukuphepha okuphezulu kukagesi we-nickel-metal hydride, impilo yomjikelezo omude, i-electrode yayo enhle eyenziwe ngama-nickel spheres, i-electrode negative esebenzayo isekelwa i-hydrogen storage alloy, ingeyezinto ezinzile, i-electrolyte yamanzi inomphumela omuhle. izakhiwo ezivimba amalangabi, ngeke ziqhume futhi zishise izingozi, ukuminyana kwebhethri monomer okungafika ku-140wh/kg; impilo yomjikelezo efika ku-3,000, ukushaja okungajulile nokukhipha umjikelezo wombuso kuze kufike ezikhathini eziyi-10,000 noma ngaphezulu; ingasetshenziswa izikhathi ezingaphezu kuka-10,000; ingasetshenziswa izikhathi ezingaphezu kuka-10,000. Izikhathi ezingaphezu kuka-10,000; ingagcina izinga eliphezulu lokushaja nokukhipha ku -40°C ~ 60°C imvelo. I-Toyota HEV car sales global ifinyelele ngaphezu kwezigidi ezingu-18, futhi ifakwe kabanzi ngamabhethri e-nickel-metal hydride, akukaze kube khona icala elilodwa lezingozi zokusha kwebhethri, ukuphepha okuphezulu kwebhethri kuqinisekiswe ngokugcwele.
Ngaphezu kwalokho, ukushaja nokukhipha ibhethri kungukuguqulwa kwamandla amakhemikhali namandla kagesi, izinga lokushisa linomthelela omkhulu ekuphenduleni kwamakhemikhali. Iziteshi zikagesi zokugcina amandla ngokuvamile zingaphandle, izinhlobo eziningi zamabhethri zithintwa indawo ezungezile nezinga lokushisa, zikhawulela indawo yeziteshi zikagesi futhi zenza buthaka indima yokugcina amandla. Amabhethri e-nickel-metal hydride emazingeni okushisa aphansi kakhulu kanye nokushisa okuphezulu kakhulu ukushaja nokusebenza kahle kokukhipha amandla, ukuze indawo yesiteshi samandla okugcina amandla iguquguquke, ilula, isebenze kangcono, eseyibambe iqhaza emqhudelwaneni wezindlela ezahlukahlukene zobuchwepheshe bebhethri " plus amaphuzu".
Eqinisweni, amabhethri e-nickel-metal hydride ekusetshenzisweni kwemakethe yokugcina amandla abe yisibonelo. 2020, inkampani yokugcina amandla ebhethri ye-nickel-metal hydride i-Nilar yi-European Investment Bank utshalomali lwama-euro ayizigidi ezingama-47. Kuyaqondakala ukuthi u-Nilar ugxile ekuhlanganisweni nasekugcinweni kwamandla okuvuselela amandla, amandla okulinda kanye nezicelo zokushaja izimoto zikagesi, ukutshalwa kwezimali ukukhuthaza inkampani izohlanganiswa nebhethri yezinhlelo zokuhlala, ezentengiselwano nezimboni kanye nezinga legridi noma izimakethe zengqalasizinda. . Ngokusho kweFrontiers in Polymer Science, ithimba likaSolwazi Yi Cui eYunivesithi yaseStanford lenze ibhethri le-nickel-metal hydride (Ni-MH) lamandla amakhulu avuselelekayo nokugcinwa kwezinhlelo zokusebenza, ngezinzuzo zempilo yesevisi yesikhathi eside, akukho bungozi umlilo noma ukushisa okushisayo, asikho isidingo sokunakekelwa okujwayelekile, ukuziphatha okuhle kwezinga lokushisa eliphansi, kanye nezindleko eziphansi. Ithimba likaCui lizokwakha iyunithi yokuhlola enamandla okugcina ama-megawatts angu-2 ngo-2021, futhi lihlela ukwandisa umthamo walo lifike izikhathi ezingama-20 kuleso samba ngo-2022.
